Research Centre for Robotics

Robotics is the branch of mechanical engineering, electrical engineering and computer science that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing.

A robotics engineer is a behind the scenes designer who is responsible for creating robots and robotic systems that are able to perform duties that humans are either unable or prefer not to complete for a variety of reasons. Through their creations, a robotics engineer helps to make jobs safer, easier, and more efficient, particularly in the manufacturing industry.

The goal of the Robotics Research Center is to encourage and facilitate fundamental robotics research, both theoretical and experimental. Participants are exploring basic issues in manipulation, mobile robotics, manufacturing, control, motion planning, graphics, and other topics.

Artificial Intelligence

Artificial intelligence is the intelligence exhibited by machines or software. It is an academic field of study which studies the goal of creating intelligence, whether in emulating human-like intelligence or not. Major AI researchers and textbooks define this field as "the study and design of intelligent agents", where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. We are trying to create a software to understand when the driver wants to go towards a certain object, like a table or a chair. Even if this is an amazing process, the EEG has a rather limited accuracy, and only a few commands are detectable. The more shared control you have, the better the brain-computer interface, and the faster the person can get from one place to another

Parallel Mechanism

Parallel mechanisms are found as positioning platforms in several applications in robotics and production engineering. Today there are various types of these mechanisms based on the structure, type of joints and degree of freedom. An important and basic planar mechanism providing three degree of freedom at the end-effector (movable platform) is a 3-RPR linkage. Here the underscore below P indicates the presence of actuated prismatic joints and 3 indicates the number of legs used to carry the mobile platform. A lot of work has been done on this mechanism since 1988. In the present work, the kinematics of 3-RPR linkage is specifically studied to understand the synthesis procedure. The forward kinematics in parallel mechanisms is a multi-solution problem and involves cumbersome calculations compared to inverse kinematics. In inverse kinematics, we design the actuator input kinematic parameters for a known table center coordinates. In other words it is a transformation of platform pose vector to the actuator degrees of freedom. In 3-RPR mechanism considered in present task, the actuators are sliders and hence the slider displacements reflect the input degrees of freedom. On the other hand, for a known posture (available slider displacement status), the table center coordinates are predicted in forward kinematics. In present work, forward kinematics solutions are obtained by defining error function and optimizing it using genetic algorithms programs. Also, the workspace and Jacobian matrices are computed at corresponding solution and singularity analysis is briefly highlighted. Main objective is to fabricate a scaled model of this planar manipulation mechanism with calculated dimensions and observe the practical workspace obtained. An attempt is made in this line to some extent. The objective is to optimize the different length ratios of the mechanism in order to have a reduced torque required for the bending motions. The parallel system is compared with the serial mechanism equipped with a pitch and roll revolute joints with concurrent concurring rotation axes.

Human-Robot Co-Operation

Robots are now physically capable of locomotion, object manipulation, and an essentially unlimited set of sensory motor behaviors. This sets the scene for the corresponding technical challenge: how can non-specialist human users interact with these robots for human robot cooperation? Children with autism are unique; with their own personality, their own interests, their own world...Even if many of them are attracted by robots, they still need personalized education. NAO is an innovative aid for these children. We are combining our research from brain psychology of these children from Autism Centers and we combine our research to build a program capable to learn and respond to surrounding for the children in need for our special care.

3D – Sensing

A 3D scanner is a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital three-dimensional models. Many different technologies can be used to build these 3D-scanning devices; each technology comes with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitized are still present, for example, optical technologies encounter many difficulties with shiny, mirroring or transparent objects. For example, industrial computed tomography scanning can be used to construct digital 3D models, applying non-destructive testing. Collected 3D data is useful for a wide variety of applications. These devices are used extensively by the entertainment industry in the production of movies and video games. Other common applications of this technology include industrial design, orthotics and prosthetics, reverse engineering and prototyping, quality control/inspection and documentation of cultural artifacts.

Robot with Soft Touch

Soft robots enjoy several significant advantages over traditional hard-material robots. The inflatable design of soft robots minimizes if not outright eliminates the risk of injury upon accidental contact. And the robots lightweight design gives it greater flexibility along with gains in speed and agility. Lightweight joints are inexpensive to make and their membrane material keeps mass density and overall weight of the robotics structure low. The result is an inflatable, versatile, and programmable arm that has taken a novel approach to making robots gentle enough to physically interact with humans. We are trying to achieve though it is theory ;When pressure is applied to the surface of one of the sensors, their pliable half-sphere shape is slightly deformed, an action which instantly changes this distribution of infrared light from the LED inside. Photodiodes at the base of the sensor pick this up so that a clever piece of software may calculate the deformation and, therefore, the force currently being exerted on the sensors by an object. The electronics, indeed, consist of standard components -- it's the type and combination of silicone layers above the PCB that the team is working hardest to customize. Soon planning to make a prototype from this concept and research which is undergoing.

Prosthesis

When the i-LIMB hand debuted in the United Kingdom in July 2007, people caught a glimpse of the future of robotic prosthetics. The i-LIMB applies myoelectric technology, where the prefix myo- denotes a relationship to muscle. Myoelectric prosthesis are controlled by placing muscle sensors against the skin at the site of amputation. The electric signals generated by the muscle at an amputee’s stump controls a processor aboard the prosthetic. This myoelectric technology allows for greater control and precision in the five fully functional digits, enabling recipients to perform everyday tasks such as picking up coins and opening tabbed aluminum cans. Trying to learn and recreate this technology at our research labs we seek to add capability to sense temperature and texture of its surroundings and send the information to a processor which will convert and send signals to the limb and therefore reach brain. We hope in completing this task as soon as possible so as to bring back the natural order in the amputees’ life.
